Question

I want to do only the one thing in that cycle … – the IF or the ELSE .. (when its true and false ofc as you know it ..) If i have two typed students with their information and my first student in group 1 is not with an excellent grade and the second one student is with excellent grade my program prints:
1)first loop on for:it;s false so it makes the else
2)second loop on for: it’s true so it makes the if

and i have:
No information
Student with excellent grade…

I want to see only the students with excellent grade (if i use BREAK; i will stop the FOR cycle) Here is my code:

int gr;
cout<<"Enter group that you want to check: ";cin>>gr;
cout<<"Students with excellent grade in group "<<gr<<":\n";
    for(i=0;i<n;i++)
        {
            if(m[i][2]==gr && m[i][3]>=5.500)
            {
                for(j=0;j<4;j++)
                    cout<<setprecision(8)<<m[i][j]<<"\t";
            }
            else
                    cout<<"No students with excellent grade in this group"<<endl;

        }

I have the same problem here. Can i use the “bool” type and how in that code(code is based on struct):

int x;
bool no_info=false;
p: cout<<"| What personal id you want to search for: ";cin>>x;

for(int i=0;i<n;i++)
{
  if(pov[i].id==x)
  {
    no_info=true;
    cout<<pov[i].id<<endl;
    cout<<pov[i].name<<endl;
    cout<<pov[i].lastname<<endl;
    cout<<pov[i].department<<endl;
    cout<<pov[i].salary<<endl;
  }
}
  if(no_info){
   cout<<"No information"<<endl;}
 goto p;

EDITED!!!

It is hard to understand what you are trying to achieve. But I think what you want is:

int gr;
bool no_excellents = true;
cout<<"Enter group that you want to check: ";cin>>gr;
cout<<"Students with excellent grade in group "<<gr<<":\n";
for(i=0;i<n;i++)
{
    if(m[i][2]==gr && m[i][3]>=5.500)
    {
       no_excellents = false;
       for(j=0;j<4;j++)
           cout<<setprecision(8)<<m[i][j]<<"\t";
    }
}

if(no_excellents)
{
    cout<<"No students with excellent grade in this group"<<endl;
}

This will not stop your for loop, and will only print those students who have excellent grades. If nobody has excellent grades, the program will tell you so.
